Zextras guide to Zimbra command line import and export shows the export as one command, zmmailbox getRestURL '/?fmt=tgz' and the import as the matching postRestURL command back into Zimbra. Aspose overview of Zimbra TGZ files lists mail, Contacts and Calendar folders inside the archive. Nothing in that route opens the archive in Outlook so Corbett converts it into a PST or any format you need.
Related pages include PST Converter, EML Converter and MBOX Converter. Other mail files sit on email converter tool page.

Corbett Zimbra Converter Tool Worked Well for me. This software allows me to export the Zimbra TGZ file without any error. Additionally, I loved the simple way to execute the conversion process with advance data filters. Thank you for this secure and advance automated solution.
Incredible Software! The TGZ File Converter performs the Zimbra conversion efficiently. It allows me to export associated email addresses and contacts. I tried the demo edition of the software and purchased the licensed key to perform conversion of over 1000 Zimbra emails.
The Zimbra TGZ Converter is an all-in-one solution for us. It helps us to export the complete Zimbra Database to cloud platforms. My business has been using Zimbra for the last five years, and we are planning to switch, and this software made it possible. Great way to convert your data files.
Before conversion
Three short checks keep your Zimbra conversion clean.
Copy the TGZ file first
Store a copy of every TGZ archive on a safe drive. Corbett opens files in view mode and a spare copy protects the original.
Export one TGZ per user
Zextras guide to Zimbra command line import and export shows the export command for a mailbox. Repeat it for every account, name files by email address and keep them in one folder.
Choose mailbox or archive
Use a TGZ file when the Zimbra server is gone. Use a live login when the server is up so Zimbra TGZ converter opens the mailbox as it stands today.
User lists come out through Export Zimbra users to CSV.
Best practice
Your conversion only helps if your mail arrives in full. Four habits keep your data safe through it.
Backup first
Copy your original TGZ files before you start. Keep 3 copies on 2 types of media with 1 copy off site.
Start with one mailbox
Convert one small TGZ file with Zimbra TGZ conversion software and open a few emails in your new format. Catch a wrong setting before a large job.
Check the count
Compare the message count in the folder tree with the mail in your output before you close the job.
Keep originals until checked
Store your source TGZ files until counts match. Delete them only after you open converted mail.
